My invention relates to a rotor construction for mechanical gas cleaners, and has particular reference to an improvement in a washer commonly known asthe Thiesen type of gas cleaner-and disintegratort The primary object of my invention is the provision of a beateror blade construction whichis removably secured to the rotary-element 1n the gas cleaner which disintegrates the gas and brings the cleansing medium and the gas into close relationship with each other whereby the particles of dirt are re moved from the gas passage, and which,

when broken, can be easily and quickly replaced without replacing the rotor plates.

In securing these blades or cleaning members in position in the rotarylement; it has. been the'practice heretofore to cast the cage? and'rotary element in one piece "so 'thatif it became necessary to remove the blades the entire structure had to be replaced, In common practice the rings in whichtliese blades were mounted were cast around the blades: which had been placed in stable positionin the moldso that the molten metal in cooling held the blades firmly in position; If

one of theseblades became broken or muti lated in suchmanner that it would not per-1 form its function, an entire new member would have to be supplied. In myimproved structure, if a blade becomes damaged "or multilated in such 'manner that it will not structure or providing an entirely new structure.

These and other objects w'll be more'fully and better understood by reference to the sheet of drawings, in which Figure 1 is an elevational view partially in section of a gas washer;

Referring now 'specifically'to the drawings,

and inlwhich like" reference characters refer t'o'like parts throughout, a casing 10 is shown having'a'gas inletk(n'ot shown) at one side thereof, and having a gas outlet 11 therefrom with a shaft 12 mounted therein in bearings 13, 13, which is driven by a motor or other suitable-me ans; The shaft '12 extends through the casing 10 and has a'circular-plate member 14 mounted thereon at -the central portion of the casing-with -paddles 15, 15- mounted thereon'adapted to a beat the gas and force it-th'rough'the container, and also has a cylindricalmember 16 mounted thereon having openings in "the walls thereof through which water, which .is conducted into the casing through water supply pipes 17 and 18 respectively, is mixed with the gas pass- 19,- 19 are" provided at the bottom -'of theing "through the casing. Water outlet pip s casing through which water flows carrying V with it the dirt particles which are removed from-thegas. 3 e 1 v 'Attached to the platemen'iber 14: 'and'ex:

tending outward therefrom in each direction is a plurality of blades 20, 20 which, together with othe'r blades extending in annward direction fr'om the outer side of the casing,

forms a beating arrangement which in-elfect is a cage formation,an'd it is with these blades that my invention has particularly 1 pair of plates21 and 22 are provided which arefcircular inform and which are'secured to .the melnber 14 by means of aplura'lity of;bolts 23,'23.' Holes 24, 24 are formed in the plates 21 and 22 respectively, within which the blades 20 are mounted. The blades 20,420 are formed insets in" the embodiment shown, foursets of blades being provided on each "side of the plate" 14, the blades being in radial. spaced, relationwith each other. and V Rings 25, 25 are provided which are secured to the outer ends of the blades 20 and serve to stiffen and hold these blades in proper alignment so they will not engage the stationary blades, sets of which are placed between the sets of rotatable blades 20, 20.

A pair of circular plates'26 and 27 are provided which are secured to the outer wall of the casing and which have a plurality of bars 28, 28 mounted therein which extend inwardly and terminateadjacent' the plates 21 and 22, with a plurality of rings 29, 29 being secured to the inner ends of the members 28 so that they are also held in proper spaced alignment with respect to the rotatable blades 20 20. V

ln making the plates 21 and blades 20 it has been the common practice heretofore to cast the plates 21with the. blades being inserted in position in the mold in whlch the plates arecast and the moltenmetal poured into the mold, so that when the metal hardens the blades 20, 20 are in position in the plates 21 and 22. This practice has been objectionable because if the blades become brokenor distorted it has been impossible to remove them from the plates 21 and22, andan entire new unit has had to be built and the old unit discarded. v

In Figures 4 to 7 inclusive is illustrated a form of the blade20 which I employ in my improved construction and which comprises a reinforcing member 30which is rectangular 32 is formed-thereon at one of the ends, with a shoulder 33 being provided adjacent the trunnion. portion 32 with a cupped end 34-being provided; The openings 24, 24 which are formed inthe circular plates 21 and-.22 are of substantially the same contour as the trunnions 32,.formed on the ends of the; blades and. formed of a sufficient size so that the blades are driven into the holes 24 in the plates 21 and ,22 andthe, vcuppedends. 34

peened over 'with a hammer, thereby fixing the blades firmly in position in the plates 21 and 22. The holes 24 are slightly countersunk at one side so that a smoothinner face is formed on the plates 21 and 22 so that they engage firmly against the side of the member 14. I

With this form of device it will be understood that if one of the blades 20 becomes broken or distorted in service it is only said necessary to remove the plates'21 and 22 from the casing, the broken blade removed, and a new blade inserted in place by the operation hereinabove described.

While I have described more or less precisely the details of construction, I do not wish to beunderstood as limiting myself thereto, as I contemplate-changes in form and the proportion of parts and the substitution of equivalents as circumstances. may suggest-or render expedient withoutdeparting from the spirit or scope of my invention.
